Some informal observations:
WavPack took longest to encode, nothing else came close.
TAK was the quickest to encode.
However...
WavPack decompressed very quickly, and eventhough my hard drive was very busy writing 2 gigs of wav files, the cpu wasn't flooded at all.
TAK on the other hand was much slower than WavPack in decoding and flooded my CPU
Here is the shntool info output of the original wav files that I decompressed from the original flac files. The original recording comes packed in flac 1.1.2:
